Ah yes, the Satan notion

When something positive happens, God did it - when something negative happens, Satan did it. Apparently we didn't much and are therefore not to blame.

Anyway......

... the Satan notion equals the Bogeyman notion (or the God notion for that matter), those who believe in their existence are affected by it, those who don't are not.

Let's see what can be inferred from the above implication......

... assertions involving the invisible Satan, Bogeyman or God proposition are cases of reification or hypostatization also known as anthropomorphization acknowledging the proposition cannot stand on its own rendering these assertions invalid and the biblical God, Satan, the socio-psychological Bogeyman therefore fictional; mere notions; memes, albeit very powerful ones.

If assertions can only be accepted on faith, then it is conceded what is proposed cannot be taken on its own merits.

The simple believeth every word: but the prudent man looketh well to his going. Prove all things; hold fast that which is good. - The Bible
